Abstract: A method of making a fibrous sheet includes providing a first furnish including a primary pulp having papermaking fibers, the papermaking fibers (i) having a weight-weighted average fiber length between about two and seven tenths millimeters and about three millimeters, (ii) a coarseness of about sixteen milligrams per one hundred meters or lower, and (iii) being at least eighty percent of the papermaking fibers of the first furnish, forming a nascent web having at least two layers, one of the at least two layers being (i) a surface layer of the nascent web and (ii) formed from the first furnish, dewatering the nascent web to form a dewatered web, applying the surface layer of the dewatered web to the outer surface of a Yankee drum of a Yankee dryer, and drying the dewatered web with the Yankee dryer to form a fibrous sheet.

Abstract: Paper products and methods of making the paper products. The paper product includes a first stratified base sheet and a second stratified base sheet. At least about eighty percent of the papermaking fibers in an outer layer of each of the first stratified base sheet and the second stratified base sheet has (i) a weight-weighted average fiber length between about two and seven tenths millimeters and about three millimeters and (ii) a coarseness of about sixteen milligrams per one hundred meters or lower. An inner layer of the second stratified base sheet is attached to the inner layer of the first stratified base sheet. The paper product has a CD wet/dry tensile ratio between about twenty-five hundredths and about thirty-five hundredths.

Abstract: Multi-ply paper products and methods of making such products includes providing a first furnish including a primary pulp having papermaking fibers with a weight-weighted average fiber length, a coarseness of about sixteen milligrams per one hundred meters or lower, and being at least eighty percent of the papermaking fibers of the first furnish, forming a nascent web having at least two layers, one of the layers being a surface layer of the nascent web and formed from the first furnish, dewatering the nascent web to form a dewatered web, and drying the dewatered web to form a multi-ply paper product. The multi-ply paper product includes a first ply and a second ply arranged such that an inner layer of the first ply is adjacent to an inner layer of the second ply and the inner layer of the first ply is attached to the inner layer of the second ply.

Abstract: A belt for creping a web in a papermaking process. The belt includes a surface onto which the web is transferred during the papermaking process. A plurality of openings extend through the surface, with the openings being arranged in lines that are offset from lines in the machine direction (MD) and cross-machine direction (CD) of the belt. Paper products, such as absorbent sheets, made from the belt have hollow dome regions and connecting regions between the domes, with the domes being arranged in lines that are offset from lines in the MD and CD of the paper products.

Abstract: A method of making a molded paper web includes bringing a permeable patterned surface of a patterned cylinder into contact with a nascent web and conveying the nascent web between a transfer surface and the permeable patterned surface over an arc length of the permeable patterned surface. The arc length forms at least a portion of a molding zone. The method also includes applying a vacuum over at least a portion of the arc length. The method further includes transferring the nascent web from the transfer surface to the permeable patterned surface of the patterned cylinder in the molding zone. The vacuum is applied during the transferring of the nascent web from the transfer surface to the permeable patterned surface of the patterned cylinder.
